Jian He commented on YARN-2157:
-------------------------------
Thanks for the patch! Some suggestions on the patch:
ClusterMetrics shows the metrics of the YARN cluster? such as…
{code}
ClusterMetrics shows the statistics of NodeManagers from the
+ ResourceManager's perspective
{code}
Do you mean the queue name? if so, we can use queue name.
{code}
queue identifier
{code}
Can you clarify more about what this format means?
{code}
<<<running_>>><num>
{code}
Can you please clarify the definition of pending applications? i.e. an
application that has not yet been assigned any containers.
Total number of applications killed -> Total number of killed applications,
similarly for “Total number of applications failed”
can you clarify the meaning of PendingMB, PendingVCores, PendingContainers
also? i.e. the pending resource requests that are not yet fulfilled by the
scheduler.
allocatedContainers can be put before allocatedGB for consistency.
{code}
+*-------------------------------------+--------------------------------------+
+|<<<allocatedGB>>> | Current allocated memory in GB
+*-------------------------------------+--------------------------------------+
+|<<<allocatedContainers>>> | Current number of allocated containers
+*-------------------------------------+--------------------------------------+
